Design of Anchor Reinforcement in Concrete Pedestals According Appendix D of the ACI 318-0



BSTRACT

Even though the Appendix D of the ACI 318-05 permits the use of supplementary

reinforcement to restrain concrete breakout, it does not provide specific guidelines in

designing such reinforcement. This paper presents a method for designing anchor

reinforcement in concrete pedestals, where un-reinforced concrete is insufficient to resist

anchor forces. Anchor reinforcement consists of longitudinal rebar and ties to carry

anchor tension forces and shear forces, respectively. The Strut-and-Tie Model is

proposed to analyze shear force transfer from anchors to pedestal and to design the

required amount of shear reinforcement. A proposed design procedure is illustrated in an

example problem
